well, gas mileage isnt too big a problem because the multifuel adapts to alternative fuels without too much modification (waste motor oil, waste veggie oil, etc). those harbor freight cargo cranes can be mounted in the bed for cheap (or, you know, a ramp or something), you dont park something like that inside simply because who the hell cares if it gets snowed on? and full set of 6 Super Single tires are actually ~$500
